OpenShack Morse Code Trainer

Learn Morse code from scratch, or sharpen your CW copying and sending. Beginners can start with step-by-step listening lessons. Experienced operators can go straight to character groups, words and callsigns at higher speeds, and refine their sending with timing feedback. OpenShack Morse Code Trainer brings beginner lessons and advanced practice together in one app for iPhone and iPad. No radio or extra hardware is needed to begin. The interface is in English. START SMALL. BUILD YOUR SKILLS. Begin in Learn Morse Code with a small set of characters. Listen to their sounds, type what you hear and add new characters as your accuracy improves. These are Koch lessons: learn the sound of each character through practice, rather than memorising a whole chart at once. Revisit earlier lessons whenever you want. GIVE YOURSELF TIME TO LISTEN Choose a speed that suits you. Need longer to recognise each character? Add more space between characters while keeping their individual sounds at your chosen speed. This is called Farnsworth spacing, and you can reduce it as you become more confident. SEE WHAT TO PRACTISE NEXT Review your accuracy and the characters that need more attention. Your lessons, settings and progress stay on your device, ready for your next session. KEEP GOING AS YOU IMPROVE Go straight to Advanced Practice for characters, groups, words and amateur-radio callsigns. Work on speed and accuracy without completing beginner lessons first, or return to them whenever you want. The two modes keep separate profiles, so advanced practice does not overwrite your lesson progress. Switch modes using the selector at the top of the trainer. TRY SENDING, TOO Use the on-screen straight key or iambic paddles to practise sending CW, with timing feedback for your short and long elements and the spaces between them. A compatible OpenShack Box can optionally connect your own physical paddle. MAKE PRACTICE PART OF YOUR DAY Practise offline on your iPhone or iPad. Adjust the tone, volume and session settings to suit you. No ads, no subscription and no account required: one app purchase includes both trainer modes. Training stops when you leave the app or lock the screen. Keep a copy of your progress with profile export and import, including compatible OpenShack desktop trainer profiles. The About screen links to the manual and further help. Training results are not posted to public leaderboards. HARDWARE AND AUDIO The OpenShack Box is optional and sold separately. Compatible BLE firmware or a Network Box connection is required; generic USB serial keyers are not supported on iOS. Listening and on-screen sending practice need no external hardware. Network Box connections and website links require internet access. Disconnect optional keyer hardware from radio/RF outputs during practice. Raise media volume to hear Morse tones, including when Silent Mode is enabled. From your first characters to faster copying and cleaner sending: make your next practice session count.
